2019-6-21  Due to the mining process, any transaction is added to the blockchain only after validation. This helps prevent fake or fraudulent transactions. Due to the constant growth in the number of miners and the increasing complexity of calculations, mining is no longer seen as just a means to make money. It has become a competition as only the first ...

As the main objective of this study, outcomes from process mining were used in a layout optimization problem in Section 3. Finally, Section 4 concludes the paper. 2.

2016-2-18  Rock engineering aspects of a modified mining sequence in a dip pillar layout The energy release rate (ERR) concept was introduced in the 1960s and is essentially a measure of stress concentration. The expected correlation with seismicity and mining conditions was illustrated by a number of workers (e.g. see Jager and Ryder, 1999). ERR cannot ...

2009-8-27  Layout 2 was also compared to conventional mining and it was concluded to be more economically feasible. However the latter is a proven mining method in these conditions and has a lower risk operational failure. Bord-and-pillar mining has some favourable promises such as improving labour difficulties, lowering operating costs and
